An endangered species, the pygmy three-toed sloth is characterised by usually blotchy, pale grey-brown fur and a tan-coloured face with a distinctive dark band across the forehead, from which long, shaggy hair hangs over the face, giving a hooded appearance.

Sloths have an unusual means of camouflage to avoid perdition; their outer fur is often coated in algae, giving the pelage a greenish tint that helps hide them in their forest habitat.

Others, like the two month old cheetah hiding under a wheel in Kenya's Masa Mara, and the grizzly bear in the snow North America, simply use their cunning and guile to remain hidden.

With special resemblance animals use a combination of colour, shape and behaviour to help them appear like something in their habitat.

Usually found wherever there are yellow and white flowers, especially goldenrod and daisies, they eat insects, either by hunting on the ground, or by ambushing from a flower.
